"We replaced the original roof on our house. I expressed my concerns about re-installation of the lightening rods to my roofer. We have had at least three direct hits since they were originally installed in 2013. My roofer called William who was very helpful. William offered to come out an make sure everything was 100% after re-installation. He came the day after I called and I'm glad he did. While the reinstall was the best he had seen (his words) there were issues after 5 year and 3 strikes that needed addressed. He fixed those and now I have a new roof and I am certain the lightening rods will work as intended. Highly recommend this company."

"I had a federal pacific panel replaced. The technician and work were professional. However, I explained to the technician that I lost power in a large section of wall. After the job was complete, I found I still didn’t have power in the wall. Now I’m being told it is a separate job and cost. An explanation before having the work done about it being a separate problem and needing additional work would have been very helpful. All I’m told now is they can come out for a service call which is $212 plus whatever the issue is. This was a miscommunication error on Mr. Electrics side. I informed the tech about the problem and there was no testing on the wall afterwards. Very disappointed."

Electrical questions, answered by experts

GFCI stands for ground fault circuit interrupter, which means it has the ability to detect a ground fault and shut the circuit down before it creates hazards. General breakers may also do that because ground faults can cause overloads, but they’re more focused on amp overloads from any cause. GFCIs are often installed in specific outlets, but breakers can come with GFCI capabilities built in for broader ground fault protection.

Replacing the panel itself takes four to eight hours of work by a professional. However, if associated wiring and related components also require replacement, the labor time increases to 20 to 30 hours. Your electrician can speed up the process by bringing in a team of pros to handle ancillary tasks.

You can determine what size generator you need for a transfer switch by matching the switch to the largest outlet on your generator. Larger generators can power up to 10 circuits, while most 5,000-watt generators can provide power to six circuits. So, if your generator’s largest outlet is 30 amps, you’ll need a 30-amp transfer switch.

When wondering what size of breaker for a water heater is appropriate, the majority of hot water heaters need a 30-amp, two-pole breaker. Most residential water heaters use 240 volts and between 3,500 and 5,500 watts. If your appliance matches these measurements, a 30-amp breaker is likely perfect. Owners of point-of-use water heaters using 120 volts and between 1,500 and 3,000 watts often find that a 30-amp breaker is adequate. Water heaters that use more watts than average may need a 40-amp breaker. Smaller units that use fewer watts could potentially use a 20-amp breaker.

There are many signs it is time to replace an electrical panel, starting with flickering lights. Other tell-tale signals include overheating appliances, light fixtures that cause an electric shock, hissing or crackling from the breaker box, burned or blackened spots near the breaker box, and breakers that trip whenever activating power-hungry appliances like microwaves.
